This isn’t the end, because negotiations, budgets and other considerations will still come into play. If that pick does stand, it would keep the Flanker family as the backbone of the TNI-AU, but the fleet would also be fragmented among 3+ types with partial commonality at best: 5 Su27SKM, 11 Su-30 (2 MKs, 9 MK2s), and 16 Su-35SK. The Su-27SKM and Su-30MK fighters will retire first, which will simplify matters, but that’s unlikely to happen before 2025 or so.

A $192 million contract began to address that in 2003, by buying 2 SU-27SK single-seat and 2 SU-30MK twin-seat multi-role fighters from Russia. Indonesia submitted a formal request to buy 24 used F-16s in 2011, but it isn’t backing away from its high-end Flanker fleet. In fact, the TNI-AU has steadily added more. Now, they’re reaching out to their neighbors for training and support.
